A house that is not the owner's primary residence pays more for the same federal flood policy, in two ways. Its premium can rise by up to 25 % a year toward the full-risk price instead of 18 %, because 42 U.S.C. 4014(a)(2)(A) lists "any residential property which is not the primary residence of an individual" among the properties on the faster track. And it pays the HFIAA surcharge of $250 a year instead of $25, a difference of $225 that no cap limits. A primary residence, in FEMA's manual, is a home where the policyholder or the policyholder's spouse lives. Vacation homes, seasonal cottages and houses rented to tenants fall outside it. On a new policy, a pre-FIRM second home gets no Pre-FIRM discount. Starting from the national gap between the median bill and its full-risk bill, the same premium reaches full price in 1 renewals on the 25 % track against 2 for a main home. 17 % of single-family policies in force on July 31, 2026 were not on a primary residence.
Which homes are on the 25 % track
The yearly cap of 18 % in 42 U.S.C. 4015(e) excludes the properties described in 42 U.S.C. 4014(a)(2), which instead climb by 25 % a year until they reach their full-risk premium. The first category of that list is a residential property that is not anyone's primary residence. The others are severe repetitive loss properties, properties whose flood claims have equaled or exceeded their market value, business properties, and buildings substantially damaged or improved by more than 50 % of their market value since July 6, 2012. A second home can fall into more than one category; the rate of climb is the same.
FEMA's manual defines the primary residence for the HFIAA surcharge: a single-family home, a residential unit or a two-to-four family building "in which the policyholder or the policyholder's spouse lives" (Flood Insurance Manual, Table 34). A house you rent to a tenant is not your primary residence, even if it is the tenant's.
The surcharge that never phases out
The HFIAA surcharge, set by 42 U.S.C. 4015a, is $25 a year on a primary residence and $250 on all other policies. It is a fixed charge on top of the premium, outside the yearly cap, and it does not go away once the premium reaches full risk. The Federal Policy Fee, $47, is the same on both. For a second home the fixed charges alone are $297 a year.
| Same premium gap | Main home | Second home or rental |
|---|---|---|
| First bill | $1,263 | $1,530 |
| Bill in year five | $1,305 | $1,530 |
| Five bills added up | $6,483 | $7,650 |
| Renewals before full risk | 2 | 1 |
The gap between the tracks grows with the distance to full risk. A premium that must quadruple, from $1,000 to $4,000 with the fixed charges, takes 9 renewals on the 18 % track and 8 on the 25 % track. The faster track reaches the same full-risk premium sooner; the end point differs only by the larger surcharge.
Where the most expensive bills are
The full-risk price follows the building, whoever lives in it. FEMA's rating looks at how often the place floods, the types of flooding it is exposed to (river overflow, storm surge, coastal erosion, heavy rainfall), its proximity to flood sources, and building characteristics such as the first floor height and the cost to rebuild (FEMA fact sheet on Risk Rating 2.0). In V zones, coastal high hazard areas, the median single-family bill on July 31, 2026 was $1,796, the highest of any zone type. Of the single-family policies in force that day, 17 % were not on a primary residence, and each of them climbs on the faster track.
No Pre-FIRM discount on a new policy
A building put up before its community's first flood map can receive a Pre-FIRM discount on a new federal policy only if it qualifies as a primary residence, is not a commercial property and is not a severe repetitive loss property. FEMA's manual is explicit: Pre-FIRM non-primary residences "are not eligible for a Pre-FIRM discount on a new NFIP policy". An older beach house bought as a second home and insured under a new policy is priced at its full-risk premium.
Buying a home you will not live in
A buyer can take over the seller's federal policy by assignment, or buy a new one within a year of the sale, and keep the discounted premium the seller had. But the cap is recalculated on the buyer's situation: FEMA's manual says the annual increase cap "is based on the information provided by the new owner", and the insurer validates primary residence status at the time of assignment. A house that was the seller's main home moves to the 25 % track the day it becomes your rental. The buying a house page shows the sequence for a buyer.

When a second home becomes your main home
Status follows the use of the house, not its history. An owner who moves into a former second home and makes it the place where they or their spouse live meets FEMA's definition of a primary residence; the insurer has to validate that status, and what it accepts as proof is its own decision. Once validated, the policy pays the $25 surcharge. Ask the insurer when the 18 % track starts to apply: the manual does not set a single date for every case. The rate increase page explains the cap itself, and the ZIP lookup gives the median bill around the house.
